| 摘 要： | 借助热分析仪对MMH微晶进行了TG和DTG分析,研究了MMH微晶中各种水分的相对含量。提出MMH微晶中存在4种水分,即自由水、松散吸附水和紧密吸附水、结晶水和羟基水,给出了MMH微晶的完整表达式,即 MgAl_(0.965)(OH)_(4.75)Cl_(0.145·1.70)H_2O。

| Abstract: | The relative content of water in mixed metal hydroxide (MMH) was analyzed by thcrmo-gravimetry and differential thermogravimeiry methods. It is shown that four kinds of water are existing in MMH micro-crystal, including free water, adsorbed water, crystal water, hydroxy water. The expression formula of MMH are given. |
